Haven't had much free time to be around here lately, but I'll tell you one thing that wasn't published in that article - I've also been playing with a QX6850 ES G0

At the time of publishing the article I was still under NDA, but not any more.

Ended up hitting 4609.3MHz with the QX6850 on a P5K Premium (very similar to the Deluxe) and snagged 3rd on HWBot, only to find the score is now 4th and no doubt will drop further I hope to have another run with the chip under dice and perhaps on a Gigabyte GA-P35-DS3R as it has much higher voltages available and I can get a BIOS made if there are any issues e.g. I explained how many people were pissed off about the lack of 1:1 divider on their GA-G33M-DS2R and they had a beta BIOS with the 1:1 divider available within 48 hours (should go public soon if it hasn't already) - very good to see that they listen.
